Re: Schematic Symbol questions

The machine has since been placed in service, as misplaced wires were finally tracked down and connected properly. The machine had been altered by the previous owner, either because of a switch failure, or because it was used for a specific purpose. In any case, Patio and I are proud to proclaim the...

Re: Coal purchase

Something to think about. Those of you who may have known Ernie Allen (deceased), of New Westminster, BC, likely remember that he used to burn a mix of Drumheller (bituminous) coal and foundry coke. If coke can be used, I'd have a hard time understanding why a mix of bituminous and anthracite couldn...

Re: Starrett #123 26" Vernier Caliper

Are you sure it measures 26"? The scale on a vernier is longer than the capacity, as there must be a place to the right of the jaws for the vernier scale. I suspect what you have is really a 24". That's exactly it - you can't use those extra 2" at the end, but they probably put them there so it did...

Re: Harold has surpassed 17,000 Posts

Thanks, Chris. I appreciate the kind thoughts, but I'm all the happier that we are able to serve our friends in Germany. A very welcome addition to the "family".

Re: One man's insanity---the story of an induction furnace

Thanks, Jim. That's likely to be useful when I finally start setting the two furnaces in place. Mean time, I picked up a huge radiator which will help dissipate heat. Got it at an auction, new, for only $40. A little damage to some of the fins, but that doesn't worry me. It, along with a little fres...

Re: Overbeck cylindrical grinder

I'd like to make mention that my degree of skill with electricity is relatively low. I knew that the machine was operational when it was purchased, and I'm the guy who removed it from service in the Litton plant, which was a part of the purchase agreement. Once wired (it operates on 480 volts, three...

Re: Tightening a chuck

I think it was Harold who said all three jaws of a chuck should be snugged up, not just one jaw; I did say that, but the comment was directed more towards Jacobs type chucks (drill chucks), not three jaw chucks for lathes. That said, it can still be a valid concept, as the scroll shifts with each s...

Re: Question about silver brazing

When in doubt, start at the top, then move past the depth that requires solder. Once it's fluid on top, it will follow the torch. The bleed hole isn't generally a requirement for threads, just for parts that are a slip fit. There's ample clearance for solder to flow with threads, as the major and mi...

Re: Harold has surpassed 17,000 Posts

Thanks, guys, but don't lose sight of the fact that one of the reasons this board runs so smoothly is due to the readers. We have gathered an array of individuals who are here for the right reasons, so there's not really much for a moderator to do. For that, I thank all of you, and I'm sure I speak ...

Are you sure it measures 26"? The scale on a vernier is longer than the capacity, as there must be a place to the right of the jaws for the vernier scale. I suspect what you have is really a 24". In Starrett's example, I think you'll find that the vernier scale is divided in 50's, (not 25's), so the...

Re: THE HARDINGE CHUCKER A FABULOUS MACHINE

Yep! I face that very issue as we speak. Right now, my Haas tool room mill is down, thanks to a problem with the power supply. Indications are that when a fuse in the primary side of my three phase supply opened up last winter, the spike killed the supply. From my perspective, that's likely the caus...
